Product introduction

HEC is a series of non-ionic soluble cellulose ethers, which can be dissolved in hot and cold water, and has the characteristics of thickening, suspending, adhesive, emulsion, film coating and super absorbent polymers protective colloid, which is widely used in paints, cosmetics, oil drilling and other industries.

Paint Application Guide

High thickening effect

● HEC provides excellent coating performance for the latex coating, especially the high PVC coating. There is no flocculation when the paint is thick paste.

●HEC has a higher effect of thickening, can reduce the dosage to improve the economic effectiveness of formulation, while improving the washability of the coating.

Excellent rheological properties

● In the stationary state, the product is completely dissolved, the best coating system to maintain shape and cans thickening state.
● In the tilting state, the system will maintain moderate viscosity, make the product equipped with excellent liquidity, and will not splash.
● During the brushing and roller coating, the product is easy to spread on the base  material, which will facilitate the construction. At the same time, have a good performance on anti-splash.
● Finally, when the paint coating is completed, the system viscosity can immediately resume, and the coating will be sagging at once.

Dispersion and solubility

● HEC is dissolved after a delay in processing, in the case of dry powder added, can effectively prevent caking. Ensure that HEC powder begin to hydration after fully dispersed.
● After proper surface treatment, HEC can adjust the dissolution rate and viscosity increasing speed well.

Storage stability

● HEC has good bio-stability, provide sufficient time for the paint store. Effectively prevent and pigments and filler sedimentation.

Q:Are salt baked chicken flavored powder a food additive?

Q:The disadvantages of food additives
Carcinogenic problems. Such as some artificial sweeteners, pigments and other animal experiments confirmed by carcinogenic effects. Such as creamy yellow pigment can induce rat liver cancer, sweetener Ganjing and phenylurea can also cause animal tumors. In recent years also found that the coloring agent sodium nitrite and meat, fish and other foods in the amine react to form a strong carcinogenic nitroso compounds.
Q:New car running during the first box of oil was fooled by the addition of additives how to do?
During the running of the new car, the additive should not be added. The number of miles that affect the running is not to be maintained, but no additives are added to the new car.
Q:What is the largest market for wholesale food additives in OKorder?
OKorder professional printing: envelopes notes / stickers / security labels / album / publicity single color pages / manual / form / bag / computer without carbon paper / color business card / tag / PVC VIP card IC card /
Q:Whether the cake oil belongs to the government prohibits the use of food additives
You should know that the cake oil is composed of what the composition of the material, which can be seen from the cake oil ingredients. The national standard "food hygiene standards for the use of food additives" (GB 2760-2007) did not include the cake oil, the name of the cake is the manufacturer's own trade name, rather than the scientific name, its composition is an uncertain number Know the main ingredients of the cake oil in order to check from GB 2760 can use the scope and maximum use. In Table 2 of GB 2760, there is no cake oil for the food additives allowed for pastry products (see pages 132 to 134 of this standard), and no additive with a maximum dosage of 6 g / kg
Q:Additive color mixing, or trichromatic?
Additive color theory states that RGB are the additive primaries and a mixture of these colors creates all other colors (this is in contrast to subtractive theory which uses CMY) Although RGB color space is mapped to the visual system via xyz colors, where the full circuit would be thus: RGB>xyz>x-bar,y-bar,z-bar>Yuv>RGB Our eyes actually work on a 2 channel binary system. This means that instead of having three channels of R-G-B (a component system) we have a channel for Red vs Green and a channel for Blue vs Yellow (an opposition) system. Bottom line: Since trichromatic theory includes yellow, it has to be the additive color mixing theory which, although archaic is still heavily used
Q:What is the milk flavor of the additive
There are milk flavor, plant creamer; additives to control the amount of Do not add too much,
Q:Ig is what kind of food additive
Is I + G, is a mixture of 5 'inosinic acid sodium and 5' Nucleocapsidate. Is better than the monosodium glutamate glutamic acid is difficult to mention a better fresh agent, one of the ingredients in the chicken.
Q:What food does not have artificial food additives
Looks like no, all the packaging of food, will contain a certain amount of additives, if not, and only their own hands at home to do the natural bar, in fact, as long as the amount of food additives, will not be harmful to the human body.Moreover, no food Additives, food will not have our favorite color scent.
Q:What are the commonly used tire additives?
The thermal oxidation process of organic compounds is a series of free radical chain reactions. Under the action of heat, light or oxygen, the organic molecules first break on the weakest chemical bonds to produce lively free radicals R and hydroperoxides. The hydroperoxide ROOH undergoes a decomposition reaction and also produces a hydrocarbon oxygen radical RO and a hydroxyl radical HO. These free radicals can lead to a series of free radical chain reaction, and finally lead to organic compounds and the nature of the fundamental changes in the structure. The role of antioxidants is to eliminate the free radicals, or to promote the decomposition of hydroperoxide, to prevent the chain reaction. Can eliminate free radical antioxidants are aromatic amines and hindered phenols and other compounds and their derivatives, known as the main antioxidant; can break down the antioxidant antioxidant phosphorus and phosphorus containing organic compounds, known as Auxiliary antioxidant.
